The Lutetian is, in the geologic timescale, a stage or age in the Eocene. It spans the time between 47.8 and 41.2 Ma. The Lutetian is preceded by the Ypresian and is followed by the Bartonian. Together with the Bartonian it is sometimes referred to as the Middle Eocene Subepoch.

- Spada Lake - Culmback Dam (wta.org)
Culmback Dam and Spada Lake are a lovely retreat off Highway 2, just east of Sultan and up the Sultan Basin Road. Spada Lake is a source of drinking water for the City of Everett, so in-water activities are prohibited, but there are hiking trails that circle the lake and nearby just waiting for your exploration.
